Learn the difference between 3.3V and 5V devices and logic levels. Connecting a single master to a single slave with an SPI bus requires four lines; each I2C is a fairly robust protocol, and can be used with short runs of wire (2-3m).
The I2C communication protocol combines the best features of SPI and UART. protocol, so data is transferred bit by bit along a single wire (the SDA line).
1 Apr 1995 The simple 2-wire serial I2C-bus minimizes interconnections so In the fast-mode of the I2C-bus, the protocol, format, logic levels and.
I2C tutorial: Learn all about the 2 wire I2C serial protocol. pulling the wire low causes all devices to see a low logic value — for high logic value all devices must
2 Dec 2016 I2C is basically two-wire communication protocol.It uses . The SCL clock of the I2c bus would be already synchronized by the wired and logic.

10 Jul 2008 this term is common in i2c interface.What does this mean? thx in advanced.
In this tutorial we will learn how the I2C communication protocol works, 8th bit is used for indicating whether the master will write to the slave (logic low) or read So we will use the Arduino Wire Library which has to be include in the sketch.2-wire Serial Interface. 7-bit, 8-bit, and 10-bit I2C Slave Addressing by Total Phase as a wired-AND configuration. Source: Wikipedia, Wired logic connection
The I2C bus uses two wires: serial data (SDA) and serial clock (SCL). All I2C master and slave devices are connected with only those two wires. Each device can be a transmitter, a receiver or both.
